I’ve seen this posted several times on different forums. I think it’s a very important answer to a moral dilemma. The question is simple: what happens to the unborn and children who die before they have the capacity to believe?
John Piper wrote about this, and I think his conclusion was a good one. But I think Jesus gave us a more direct answer to the question.
For the believing wife brings holiness to her marriage, and the believing husband brings holiness to his marriage. Otherwise, your children would not be holy, but now they are holy. – I Corinthians 7:14
This passage is mostly about staying true to your marriage, even if your spouse does not believe. But this verse is an interesting one. Essentially, the righteousness of one parent makes the children righteous. Seemingly, children are protected by their parents until they are old enough to believe themselves.
So if you’re holding out for a deathbed conversion: think again. The fate of your children may depend on it.
